Measuring Your Penis

Most men already know the measurements of their penis but it is
probably useful to talk a bit about how you should measure
penis width and penis length.

Length:

When the penis is in full erection, push it down until it is at a
straight angle with the body. Measure along the top from the base
until the tip.

Some people argue
over whether you should press the ruler as far as possible against
the pubic bone (bone-pressed) or just hold it loosely against the
skin where the penis meats the body. The argument rises from the
fact that overweight people lose a lot of length due to fat
build-up at the pubic bone. Pressing inside with a ruler might give
them a truer measurement although during intercourse they will not
be able to use that extra inch or two. The fairest way of measuring
is probably to hold the ruler firmly against the body without
forcing down on it.

Girth (circumference):

Measure around the thickest part
of the shaft at full erection.

Girth could also be obtained by
measuring the width, viewed from the top of the penis, but
this is not a very precise method because a penis is not perfectly round. It is usually a bit wider when
looking from the top than looking from the side. Also, a penis is not an exact cylinder.
Usually it has a thinner and a wider part. For a circle, the
circumference could be measured as diameter times pi (pi=3.1416).

Some internet
surveys say that you should measure at the widest point of the penis
anywhere along its length, including the head. Most people do agree
with that. This
could coincide with the fact that for most people the widest part is
the head. However, strictly following this rule could lead to false
figures:

Who is thicker in this
picture?

According to the above rules the right
penis is bigger
since its head is a little bigger than the widest point of
the left penis (the shaft). But the truth is that the left one
will fill up a vagina 70% more than the "bigger" one
(almost twice the volume!).
